Core Values

Sully-Miller is dedicated to enhancing the lives of our customers in the markets we serve.

With 100 years of experience, Sully-Miller Contracting Company has been integral in the growth and development of Southern California. Our customers are the people who use the roads, airports, seaports, rail and intermodal facilities, and private business infrastructure that we build and maintain.

Our Core Values provide the foundation and guidance for our employees and our business as we proudly serve our customers.


Our culture of teamwork allows us to work together within the Company and with our customers to deliver solutions and accomplish goals.


New and innovative ideas, strategies and products are encouraged as a means to improve our jobs, processes and the future of our company and society.


We will always treat employees and business associates with respect and fairness in the same manner we expect from others.


We support an environment where employees feel comfortable being themselves, which includes enjoyment in their job and interaction with their co-workers.


Trust is an essential human value that cannot be purchased but is gained through actions, not words. We must always ensure that our words match our actions, both inside and outside of our Company.

Continuous Learning

Learning and continuous improvement are critical elements of our future. We support and encourage learning through our Sully Improvement Method.
